MACHINERY FOR CLEANING 0R RENOVATING CARPETS, RUGS, AND SUCH LIKE.

Specification of Letters Patent.

Patented July 17, 1906.

To all whom it may concern:

Be it known that 1, JOHN MONTGOMERY 00L- LINS, engineer, a subject of the King of Great Britain, residing at 121 Swanston street, Bridgeton, Glasgow, Scotland, have invented certain new and useful Improvements in Machinery for Cleaning or Renovating Carpets, Rugs, and such Like, of which the following is a specification.

This invention relates to machinery for cleaning or renovating carpets, rugs, and such like; and it has for its object to improve the construction of such machinery.

In carrying out my invention I use a roller or cylinder, over which the carpet or such like is passed, and this roller, which is carried in suitable frames, is driven by worm or other gear from a power-shaft. By means of a suitable arrangement the roller can be raised or lowered to suit the nature of the material being treated. The surface of the roller is roughened, so as to grip and feed the cloth, and above it is arranged a revolving brush, which has a lateral or reciprocating motion imparted to it. The mechanism for driving this brush is or may be such that its direction of revolution is reversed at intervals. Benzin, ammonia, or other suitable detergent is fed, by means of a spray-pipe, (or pipes,) to a feeding-cover arranged over the brush and adapted to deliver the benzin thereto.

In order that my invention may be clearly understood, I have hereunto annexed two explanatory sheets of drawings, showing a convenient method of constructing the ma chine.

Figure 1 is an end elevation, Fig. 2 a side elevation, and Fig. 3 a plan, of the machine. Fig. 4 is a vertical section. Figs. 5 and 6 are sectional views of parts of the brush and its shaft.

a, is the feed-roller, over which the carpet or the like is passed, and this roller has journals at its ends, Which are carried in bearingblocks capable of sliding in vertical slots 1) in the end frames 0. The roller can be raised and lowered to suit the material being treated by means of vertical screw-spindles (1, whose screws work in the bearing-blocks aforesaid. These spindles d can be rotated when desired, so as to effect the adjustment of the roller, means of worm gear 6, driven by the shaft f, which latter can be turned by the hand-wheel g. The feed-roller is driven by thebevl-gear Zc from the main shaft Z. m represents belt-pulleys for driving the shaft Z.

a is the rotary brush,whose shaft 1) is carried in the bearings 0 on the end frames. The shaft, which is rotated by means of a chain-gear p g from the main shaft Z, has its ends carried out beyond the bearings for a short distance, as shown, and connected to rectangular blocks 7, which slide in guideways p 10'. Each slide-block is reciprocated laterally on its guideways by means of a lever 8, which at its upper end is passed through a hole in rock-bar s, fitted to the block. The lever s is pivoted at s to the bracket t, depending from the guideways, and its lower end is connected by the rod u to a crank 12 on a cross-shaft w, actuated by means of the bevel-gear a; from the shaft Z. The meclranism for effecting the reciprocation is the same at each end of the machine. The brushshaft p has a feather p on it which can slide in a keyway in the hub of the chain-wheel p, which latter is fitted loosely on the shaft and is prevented from moving laterally by a fixed bracket 19 bearing against its hub.

Each end of the shaft is connected to its slide-block r bymeansof a loose collar 1 hav ing laterally-projecting pins y, which rest in the recesses 1 of the block. The collar y rests between the fixed collars (1/ of the shaft.

The cover 2 for the liquid detergent is made of metal and in two portions 1 2, which are hinged to one another and to a longitudinal fixed rod 3, which extends from the one end frame of the machine to the other at a point above the brush. Each portion of the cover is made of a somewhat curved shape, as shown at Fig. 4, and the whole cover hangs over the top of the brush, the hinged portions being held outward and away from the brush by means of chains .2 passing over guide-pulleys carried on the roof'of the building and provided at their ends with counterbalance-weights w. The attendant by manipulating these chains can raise up and lower down the portions of the cover, as desired. The liquid detergent is forced or otherwise supplied to overhead pipes 2 with which flexible pipes 5' connect. These pipes 2 conduct the detergent to pipes .2 arranged within the cover and which are perforated, so as to deliver sprays against the sides of the cover. The detergent runs down the sides of is rotated by means of worm-gear h 'L h i, the cover and into the depressions or troughs driven from the counter-shaft which latter l 4 at the bottom and then flows onto the brush as the latter revolves. It will be seen that the edges 5 of the depressions are rounded. This is to prevent the bristles of the brush, no matter which way it is turned, catching on the edges.

The cover is made in a number of sections, each with its pipes complete, so that any one or more of the sections can be put into or out of operation, as desired. Cocks or other means would of course be provided for cutting off the supply of liquid detergent from any section.

The brush is also preferably made in anumber of sections. To do this, there are a number of cylindrical stocks a (see Fig. 6) slipped on the shaft 2), and these stocks are made in halves, which are held on the shaft and to each other by means of rings M, which lie in the grooves formed by the abutting recesses 01 at the ends of the stocks. The stocks are held pressed against one another by means of nuts and collars at the ends of the shaft. With this arrangement any one or more of the sections when worn can be removed and replaced by a new one.

-Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A carpet cleaning or renovating machine comprising, in combination, a frame with guide thereon, a roller, means for revolving the roller, a cylindrical brush mount ed on a shaft, a sliding shoe connected to one end of the shaft and working on said guide, means for reciprocating the shoe, and means for rotating the brush.

2. A carpet cleaning or renovating machine comprising, in combination, a frame with guides at each end thereof, a roller, means for revolving the roller, a cylindrical brush mounted on a shaft, sliding shoes con- 1 nected to each end of the shaft and working on said guides, means for reciprocating the shoes, and means for rotating the brush.

3. A carpet cleaning or renovating machine comprising, in combination, a frame, a roller, means for revolving the roller, a cylindrical brush mounted on a shaft carried by the frame, sliding shoes connected to each end of the shaft, guides for the shoes, levers connected with the shoes, connecting-rods jointed to the levers, crank-shafts to which said connecting -rods are connected, and means for operating said crank-shafts.

4. A carpet cleaning or renovating machine comprising, in combination, a frame, a roller, means for revolving the roller, a cylindrical brush mounted in the frame, horizontal guides projecting from each end of the frame in line with the brush, sliding shoes on the guides, a cylindrical brush mounted on a shaft whose ends project out over the guides, loose collars on the ends of the shaft, pins on the collars adapted to engage with the shoes,

a feather on the shaft, a wheel for rotating the shaft said wheel having a feather-way in its hub for the reception of the said feather, means for rotating the wheel and means for reciprocating the shoes.
